[ERROR] Error:error while loading <root>, error in opening zip file error:scala.reflect.internal.MissingRequiremen Terror:object scala.runtime in compiler mirror not found.

Compile an Apache open source project at home and encounter errors at compile time as follows:

It was compiled with the open source Carbondata project, and the use of MAVEN3.3.9,JDK was 1.8. So to the Internet various search and query see various answers, but none can solve the problem. There is a hint that a jar package corruption may have caused an error in opening. So all of the Maven repository jar is completely erased and recompiled, OK compile successfully. (You can also write code to check which jar package is broken.)

But why is the jar package damaged? I reviewed the compilation process, the original compile at the beginning of a frequent download jar package is very slow, in the process of downloading the direct interruption of the RE, it may be caused by this reason.

Compile and start running code and report the following error.

is also a variety of search, some say to download the correct winutils.exe, some say to use the command Winutils.exe to the directory to assign permissions, and some say installed XXX software conflict .... All sorts of things have been done or the same mistake. Finally reboot (restart the machine) all right.

Tears ran ...
